There are source RPMs available in the Fedora koji system at http://koji.fedoraproject.org/koji/packageinfo?packageID=1421. These can be used to produce binary RPMs packages. The three necessary packages are:

 * python-zope-interface
 * python-twisted
 * buildbot

You will likely want these optional dependencies as well:

 * python-twisted-web - for the waterfall display
 * python-twisted-mail - for status emailers

= Building RPMs =

It's most convenient to build in a non-root environment that can be created as follows:

{{{
$ mkdir -p ~/rpms/{sources,build,rpms}
$ cat > ~/.rpmmacros <<EOF
%_topdir        $HOME/rpms
%_builddir      %{_topdir}/build
%_sourcedir     %{_topdir}/sources/%{name}-%{version}
%_specdir       %{_sourcedir}

# Put directly into rpms directory, not srpms or rpms/%{arch}
%_rpmfilename   %%{NAME}-%%{VERSION}-%%{RELEASE}.%%{ARCH}.rpm
%_rpmdir        %{_topdir}/rpms
%_srcrpmdir     %{_topdir}/rpms
EOF
}}}

Note that with the `<<EOF` syntax, this produces a file with `$HOME` expanded. rpmbuild does not expand environmental variables for you.

A command sequence like the following should produce all necessary RPMs:

{{{
$ rpmbuild --rebuild --define 'dist .centos4' http://rosalyn.dyn.slamb.org/yum/centos4/SRPMS/python-zope-interface-3.0.1-3.centos4.slamb.src.rpm
$ sudo rpm -Uvh ~/rpms/rpms/python-zope-interface-3.0.1-3.centos4.slamb.x86_64.rpm
$ rpmbuild --rebuild --define 'dist .centos4' http://rosalyn.dyn.slamb.org/yum/centos4/SRPMS/python-twisted-2.4.0-1.centos4.slamb.src.rpm
$ sudo rpm -Uvh ~/rpms/rpms/http://rosalyn.dyn.slamb.org/yum/centos4/SRPMS/python-twisted-2.4.0-1.centos4.slamb.x86_64.rpm
$ rpmbuild --rebuild --define 'dist .centos4' http://rosalyn.dyn.slamb.org/yum/centos4/SRPMS/buildbot-0.7.5-1.centos4.slamb.src.rpm
}}}

Note the mixed build and installation commands - later RPMs dependent on former ones to build (test) as well as to run.

You can change the `--define 'dist .centos4'` to match your distribution or omit it entirely. It can be convenient to have the distribution name in the release (and thus filename) of packages built for that distribution.

You can examine each spec file and make alterations as follows:

{{{
$ cd ~/rpms/sources/buildbot-*
$ vim buildbot.spec
$ rpmbuild -ba buildbot.spec
}}}

= Distribution Specific Notes =
== CentOS ==
You must have python-devel installed to rebuild the [http://www.fedoraproject.org Fedora] srpm on a CentOS box ... python-devel should be in CentOS's default yum repositories. The following srpms pulled from [http://www.fedoraproject.org Fedora] and rebuild on a CentOS box is required before you can install buildbot as of 0.7.7

{{{
python-twisted-core-2.5.0-4.fc9.src.rpm
python-twisted-mail-0.4.0-4.fc9.src.rpm
python-twisted-names-0.4.0-3.fc9.src.rpm
python-twisted-web-0.7.0-3.fc9.src.rpm
python-twisted-words-0.5.0-3.fc9.src.rpm
}}}
